Trafigura's South American joint venture has begun offering a carbon-neutral freight service.
Impala Terminals said the move gives customers visibility into the indirect Scope 3 greenhouse gas (GHG) emissions generated by the transport of non-ferrous metals and minerals via container.
Clients can help offset this footprint by providing funds to carbon-finance projects across the world.
Impala is promising accurate Scope 3 calculations from the points of collection to delivery.
Earlier this year, Trafigura began a carbon-neutral freight service transporting nickel precipitates in boxes originating from Terrafame's mine and refinery in Sotkamo, Finland, to ports in China.
The CarbonNeutral Protocol — the leading global framework for carbon neutrality — has certified the service.
Colombian project
Money is going to a project aimed at protecting the Choco-Darien rainforest in Colombia from deforestation.
Trafigura said this is one of the most biologically diverse areas in the world.
The trading giant has pledged to come up with Scope 3 reduction targets by 2023.
Nicolas Konialidis, chief executive of Impala Terminals, said: "This new service complements Impala Terminals’ proactive efforts to reduce its operational emissions and manage its carbon footprint.
"We can now help our customers, including raw material suppliers for the electronics, batteries and electric vehicle industries, to measure and offset greenhouse emissions along their supply chain."
Work to continue
He added that the company would continue to identify new avenues towards a lower-carbon future.
Impala is a 50:50 joint venture with IFM Investors that owns and operates metals terminals infrastructure in Mexico, Spain and Peru.
The joint venture also includes refined products storage, distribution and river operations in Paraguay and a Swiss-based operation.
